The disc has a rod passing through it that is connected to an actuator on the outside of the valve.
													
																	Butterfly valve electric actuator. 
									
	
		
	
																	The butterfly valve regulates or isolates flow using a disk as a closing mechanism. 
																	Valworx electric actuators rotate an output drive to open and close butterfly valves. 
																	A butterfly valve is a valve used for flow regulation in large pipe diameters in which the disc takes the form of disk. 
																	Operation is similar to that of a ball valve. 
															
													
									
	
		
	
																	The belimo retrofit app enables you to find replacement solutions for sensors actuators and valves based on a variety of parameters such as manufacturer model voltage control type torque running time and close off requirements. 
																	Rotating the actuator. 
																	The actuator uses air electricity or a spring to open and close the valve. 
																	An actuator is a mechanical device for moving or controlling a mechanism or system. 
															
													
									
	
		
	
																	An actuator as part of the actuated butterfly valve typically is a mechanical device that takes energy usually created by air electricity or liquid and converts that into some kind of motion. 
																	Electric actuators provide a reliable and economical method of operating these valves from a remote location. 
																	Electrically actuated butterfly valves control the flow of material through a circular pipe or tube. 
																	For modulating valve applications an electric actuator with eps positioning can control the valve flow with a 4 20ma command signal. 
															
													
									
	
		
	
																	They are for use in controlling the flow of compressed air and other gases or for vacuum service. 
																	An actuator is a mechanism used for closing and opening a valve. 
																	A butterfly valve is a valve used for flow regulation in which the disc takes the form.
